I'll hold on to the world tight some day. I've got one finger on it now; that's a beginning.

Kill two birds with one stone, feed the homeless to the hungry.

You must never name the goal. You must never tell us the target you're hitting for. You must automatically go toward it without ever naming it.

The great thing about my life is that everything I've done is a result of what I was when I was 12 or 13.
